Impressed with K20D

We tried out the new K20D cameras today and as it was pouring with rain opted for some still life indoors. I'm very impressed with the detail and quality of the images, another step up from the K10D. Here's a sample image using the SMC Pentax-FA 100mm f2.8 Macro at f32.


Best regards, John

It would be interesting to see two images of the same with the only difference being one taken on the K10 and one on the K20. They would need to be taken in JPG to see how the camera produces its results....

RAW would also show differences between the cameras as long as the same RAW conversion settings were used.

As soon as the images are opened in Photoshop the difference between the K10D and K20D is immediately obvious. Not surprising really as the K20D resolution is significantly better.

Other factors may be the new Premium setting for JPEGs and differences in the camera's alogorithms. The setting I settled on was "Bright" which gives nice punchy results. Exposure was also better than the K10D.

I'll try and find some time to produce some comparison shots.
Best regards, John

The more pics I see from the K20D the more I realise I need to beg, borrow or steal the extra money to get one (I was going to get the K10D as they are such a good price at SRS).

The colour, clarity etc. is amazing.

John, could you give me an idea of the file sizes of the Prem jpg & Raw for the K20D, so I know what size of hard disc I'm going to need to get!

Many thanks
Steve
Smile! You could be on camera!

Adobe DNG Converter can save hard disk space as it converts PEF to compressed DNG (lossless).

It saves about 25% with K10D files. Presumably it works with K20D files too.

Based on the maximum pixels (4672x3104) the number of images on a 1GB card is approx:

RAW (PEF or DNG) 40
JPEG Premium 68
JPEG ***117
JPEG ** 212
JPEG * 411

Hope that helps!
Best regards, John

K10Ds don't have the premium setting, what, if any, improvement in JPG quality does this give over the highest setting on the K10?

Logically, it will mean less compression and therefore better quality, but until I make some A3 prints then how much better I don't know.

You won't be disapointed John, even A3 from Jpeg's are good

Thanks John, at 25mb (Raw) and 15mb (jpeg Prem) it looks like it's going to have to be a BIG portable HD needed! Or a lorry load of blank DVDs!

I couldn't wait any longer, I've ordered a K20D from SRS this afternoon!!!
Now, how do I break it to my wife that we are going to need a bigger hard disc as well!

Thanks
Steve
